-2.6*10*0.4*25.6/(-1.3*10*2*2.6)=26*4*256/(13*20*26)=256/65=3 64/65

Переведите пожалуйста:

Jason: Kirill, do you know what? Let’s watch “Pimp My Ride UK”.
Klrill: Sorry? What did you say?
Jason: I said that the car show “Pimp My Ride UK” starts on MTV right now. Would you like to watch it, too?
Kirill: Why not? What is it about?
Jason: Generally the show begins with a participant showing his or her car, and trying to convince MTV why it needs “to be pimped”.
Kirill: Sorry? Did you say “to be pimped”?
Jason: Yes, exactly. In other words, “to be restored and customized”. DJ Tim Woodman, the host of the show, comes to the participant’s house, examines the car, and takes it to a custom body shop where a team of workers and mechanics rebuilds it. At the end of the show, the car is revealed to its owner.
Kirill: I think I know the show you are talking about - "Тачку нa прокачку".
Jason: Sorry? Did you say “touch” and what?
Kirill: I was just saying that I know the show “Pimp My Ride”. I saw the American version which was broadcast on Russian TV and the name was translated like "Тачку нa прокачку!".
Jason: Oh? Was it?
